1.our welding studs have passed CE certification and ISO9000. 2.welding stud range :diameter from 6mm to25mm

WIRUN shear connectors are design to effectively tie the concrete to the steel beams and to resist shear loading between the concrete slab and steel beam in composite construction. With our stud welding equipments, the shear connectors are widely used in steel construction buildings, bridges, etc, and also act as embedment anchors on miscellaneous embedded plates, frames, angles, strip plates, etc. With the UF19B type ceramic ferrule, welding through metal deck are available for steel construction projects.

By advanced production technology and strictly inspection system, our shear connectors are meet the standard of EN ISO 13918 or AWS D1.1, both dimensions and mechanical properties are according to the above standards: Tensile strength min. 450Mpa, Yield strength min. 350Mpa, Elongation min 15 percent, etc.

Other standards or special dimensions are available on request.

Ceramic ferrule for unthreaded studs and shear connectors type UF (EN ISO 13918).Our studs have past CE certification and ISO2000 certification.
